The view controller must be a child of some UINavigationController for the .title property to take effect. If the UINavigationBar is simply a view, you need to push a navigation item containing the title, or modify the last navigation item: UINavigationItem* item = [[UINavigationItem alloc] initWithTitle:@”title text”]; … [bar pushNavigationItem:item animated:YES]; [item release]; or bar.topItem.title … Read more
In AppDelegate.swift, in application(_:didFinishLaunchingWithOptions:) I put the following: UINavigationBar.appearance().barTintColor = UIColor(red: 234.0/255.0, green: 46.0/255.0, blue: 73.0/255.0, alpha: 1.0) UINavigationBar.appearance().tintColor = UIColor.white UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white] (For Swift 4 or earlier use NSAttributedStringKey instead of NSAttributedString.Key) For titleTextAttributes, the docs say: You can specify the font, text color, text shadow color, and text shadow offset … Read more
If you’re using a navigation controller: MyViewController *_myViewController = [[MyViewController alloc] initWithNibName:@”MyViewController” bundle:nil]; [[self navigationController] pushViewController:_myViewController animated:YES]; UIBarButtonItem *_backButton = [[UIBarButtonItem alloc] initWithTitle:@”Back” style:UIBarButtonItemStyleDone target:nil action:nil]; self.navigationItem.backBarButtonItem = _backButton; [_backButton release], _backButton = nil; [_myViewController release], _myViewController = nil; If you’re not using a navigation controller, look into the Three20 style components to make custom … Read more
The best way to do this is to create a button, set its background image, and set its action. Then a UIBarButtonItem can be created using this button as the custom view. Here’s my example code: UIButton *settingsView = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 61, 30)]; [settingsView addTarget:self action:@selector(SettingsClicked) forControlEvents:UIControlEventTouchUpInside]; [settingsView setBackgroundImage:[UIImage imageNamed:@”settings”] forState:UIControlStateNormal]; UIBarButtonItem *settingsButton … Read more
Actually it is pretty easy to do. You just need to connect navigation isNavigationBarHidden property with status bar. Objective-C – (BOOL)prefersStatusBarHidden { return self.navigationController.isNavigationBarHidden; } Swift <= 2.3 override func prefersStatusBarHidden() -> Bool { return navigationController?.navigationBarHidden ?? false } Swift 3.0 override var prefersStatusBarHidden: Bool { return navigationController?.isNavigationBarHidden ?? false } And be sure you … Read more
Put this code in the view controller you want to hide the navigation bar for. – (void) viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self.navigationController setNavigationBarHidden:YES animated:animated]; } And you may also want to stick this in there, depending on your needs: – (void) viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [self.navigationController setNavigationBarHidden:NO animated:animated]; }
You can set the property barPosition to UIBarPositionTopAttached another way! Add a delegate to your UINavigationBar. Implement -positionForBar: in the delegate class: – (UIBarPosition)positionForBar:(id<UIBarPositioning>)bar { return UIBarPositionTopAttached; } Your navigation bar’s top must also be anchored to the Top Layout Guide.
I figured it out. I had to override the intrinsicContentSize getter for the view, and the text field. I set the width to CGFloat.greatestFiniteMagnitude so it’ll always be as wide as the screen. Update: Since I’ve spent couple of hours on this issue, hope that some else will catch up faster by having all things … Read more
Calling presentViewController presents the view controller modally, outside the existing navigation stack; it is not contained by your UINavigationController or any other. If you want your new view controller to have a navigation bar, you have two main options: Option 1. Push the new view controller onto your existing navigation stack, rather than presenting it … Read more
Warning will disappear if you change the property “Simulated Size” to “Freeform”.
